How to Replace a Fuel Filter in a Dodge Ram. The fuel filter in your Dodge Ram screens out dirt and rust particles from the fuel. Some mechanics recommend you replace the fuel filter every 30,000 to 40,000 miles. Follow the instructions below to replace the filter on a Dodge Ram with a gasoline engine.

Remove the fuel pump relay from the power distribution center. This will relieve the fuel system pressure. Start the engine and allow it to run until it stalls. Try to start the engine again and let it run until it stalls. Repeat this procedure until it will no longer start. Turn off the ignition.

Disconnect the negative battery cable. Then, disconnect the fuel tank and pull the filter out of the rubber grommet. Remove the fuel line after you cut the hose clamp.

Push the new fuel filter into the rubber grommet, positioning it like the filter you removed. Attach it with a new clamp.

Put the fuel tank back in place. Reconnect the negative battery cable. Start the engine of your Dodge Ram and check for leaks.


Make sure you let the pressure out of the fuel system before you disconnect the fuel lines. Take care to ensure the fuel does not get on your skin, face or eyes. Before starting your Dodge Ram, make sure you wipe up any fuel that may have spilled as you replaced the fuel filter.
